background: many epidemiological studies reported significant associations between air pollution and respiratory hos­pital admissions. proximity of industries to the residential areas may have considerable impacts on air quality and sub­sequently public health. this paper describes the indirect impacts of closing a large steel industry, broken hill proprie­tary (bhp), in the lower hunter region...

Evidence is presented to support the recent suggestion that human neural tube closure is similar to that observed in mice, and comprises several regionally distinct closure sites rather than being a simple zipping up process. Seven subjects, each with more than one neural tube defect (NTD), are described. Comparative studies of the location of the lesions in relation to the closed parts of the ...

Maternal plasma fatty acid changes were measured in early pregnancy and an increase in maternal plasma DHA concentration is initiated in human pregnancy prior to neural tube closure which occurs at 28 days' gestation.

Background Atrial septal defects (ASDs) are the most common third congenital heart defects. This study aimed to evaluate the clinical course of ASDs and the relationship between its complications, location closure and size. Materials and Methods: This cross-sectional study was conducted...

Between September 1984 and April 1987 a total of 150 patients underwent Nd-YAG laser iridotomy procedures at the Bristol Eye Hospital. Forty of these patients (27%) were treated for acute angle closure glaucoma (AACG), and three of them (7%) suffered recurrent AACG. Sixteen patients who had been treated for AACG have been challenged by a pharmacological provocative test introduced by Mapstone, ...

Semigroups with an additional unary operation called a (right) closure are investigated. These “closure semigroups” may be viewed as (not necessarily regular) generalisations of inverse semigroups, and several powerful structural aspects of inverse semigroup theory are shown to extend naturally to some important classes of closure semigroups. These include representations as partial transformat...

the emergent abdominal surgeries from either of traumatic or non traumatic causes can result in situations in which the abdominal wall cannot initially be closed. many techniques have been reported for temporary coverage of the exposed viscera, but the result of various techniques remains unclear. during 94 months, 19 critically ill patients whit an open abdomen underwent surgery using plastic ...
